Abstract (en)

[origin: EP4219623A1] The present invention relates to a thermoplastic resin composition which includes: a graft polymer including a rubber polymer having a gel content of 0 to 10 wt% and including an aromatic vinyl-based monomer unit and a diene-based monomer unit; and a shell including a (meth)acrylate-based monomer unit and an aromatic vinyl-based monomer unit grafted to the rubber polymer; and a non-grafted polymer including a (meth)acrylate-based monomer unit and an aromatic vinyl-based monomer unit, wherein refractive indices of the graft polymer and the non-grafted polymer differ by 0.0100 or less.
